  1. SPDO report Richard Schilizzi and Peter Dewdney US SKA Consortium Meeting Madison, 17 November 2008

  2. International SKA context PrepSKA SPDO and WP2, WP3 WPs 4, 5, 6, 7 SPDO team WP2 program (Peter Dewdney) Contents

  3. Top-level specifications in SKA Memo 100 Sensitivity (Aeff/Tsys) 12000 (max) FoV single pixel feed 1 sq. deg. (21 cm), 4 sq. deg. at z=1 phased array feed 20 sq. deg. aperture array 20 sq.deg. Survey speed figure of merit (Aeff/Tsys)2.FoV 2x1010 (max) Continuum sensitivity 20 nJy (10 hours) specifications

  4. Target construction cost: 1.5 billion € for Phase 1+2 Expected operating costs: 100+ million €/year Energy costs a big contributing factor Currently funded SKA R&D (2007-2012) via national and regional projects: 140 M€ PrepSKA (FP7) funds the SPDO engineers Design Studies (FP6 SKA Design Study, US Tech Dev Program) Pathfinders (ASKAP, MeerKAT, LOFAR, Apertif, ATA, MWA, LWA, EVLA, eMERLIN, eEVN) Costs

  5. 2008-2012 costed system design 2012 site selection 2012-2013 agreement on construction funding 2012-2016 Phase 1 implementation 2016  early science with Phase 1 2016-2021 construction of full array at low and mid-frequencies Key dates

  6. EC-FP7: PrepSKA System design Verification Programs Funding Governance Site Selection SKA timeline Phase 1 funding approval Phase 2 funding approval SKA-mid+low Complete Site Select Reference Design selected Phase 1 complete Preliminary SKA specs Prod.

  7. Solar power array in Portugal 2550 elements each 150 m2 Spread over an area 2km in diameter Azimuth rotation Erected in one year

  8. Artist’s impression of the SKA 1000- 1500 dishes (15m) in the central 5 km 2000-3000 total + dense and/or sparse aperture arrays

  9. Alternatively…….

  10. Formal PrepSKA partners Agencies STFC (UK), NWO (NL), CNRS (FR), INAF (IT), DIISR (AU), NRF (ZA), NRC-HIA (CA) Institutes ASTRON (NL), Cornell/NAIC (USA), CSIRO (AU), IT (PT), JIVE (Europe), MPIfR (DE), OBSPAR (FR), RuG (NL), UCal (CA), UK (UCam, UMan, UOxf), UOrl (FR), Other organisations involved in study NSF(USA), AUI(USA), FG-IGN(EC), VR(SE), SKA Program Development Office (SPDO) 7 Work Packages PrepSKA

  11. PrepSKA organisation

  12. Deliverables (Peter Dewdney “Guiding Principles, Activities and Targets for WP2”) Technology selection System Design including operational – construction tradeoffs Science Performance vs Reference Science Mission Total cost estimate for Baseline Design (incl. contingency) Risk assessment Design and deployment plan Top-level build schedule Upgrade paths WP2

  13. Streamline WP2 Description of Work Move from 40 technology development tasks, including an ill-defined ‘IVS’ to assembly and verification of large SKA sub-systems Easily evaluated by EC and Funding Agencies/Governments Dish Verification Program PAF Verification Program AA Verification Program Signal transport Verification Program ….. + MoAs with organisations and institutes WP2 approach

  14. Inform decision-making process for site selection Carry out further RFI measurements (in progress) RQZ (in progress) Investigate infrastructure deployment costs and timescales Detailed risk analysis Array configuration (in progress) Ionosphere (in progress) Tropospheric water vapour WP3 – Additional Site Studies

  15. WP4 – Governance and Legal Framework (led by NWO, NL) Study of options for viable models of governance and a legal framework for SKA during construction and operation Interim legal entity for SPDO during PrepSKA? WP5 – SKA Procurement and industrial involvement (led by INAF, Italy) Lay out options for procurement Investigation of the optimum way to involve industry in the global, regional and national contexts WP4, WP5

  16. WP6 – Developing the funding model(led by STFC, UK) Investigate all aspects of the financial model for lifetime costs of the SKA Issues: phasing of SKA and ELTs what constitutes a “mature” project? post-PrepSKA funding how to value in-kind contributions pre-construction Investigate options for loan from European Investment Bank and other similar bodies to provide a smooth funding profile WP7 – Implementation plan(led by Co-ordinator) Investigate socio-economic and knowledge impact of the SKA Integrate output of all other partners to produce a detailed, costed design for Phase 1 of the SKA and an implementation plan for the full SKA. WP6, WP7

  17. Project Director Richard Schilizzi Project Engineer Peter Dewdney Project Scientist Joe Lazio Executive Officer Colin Greenwood System Engineer Kobus Cloete Domain Specialist Receptors Neil Roddis Domain Specialist Signal Transport Roshene McCool Domain Specialist Computing & Softw Duncan Hall (starting January) Domain Specialist Signal Processing not yet filled Site Engineer Rob Millenaar Project Management Officer Billy Adams (starting January) Industry Relations Manager to be advertised Outreach Officer Ian Morison Office Manager Lisa Bell Support Engineers (4-5x) to be advertised SPDO Team

  18. Call for submissions – deadline 31 October 2008 7 responses (ASTRON, CSIRO, INAF, JPL, McGill/Laval Universities, NRAO, NRC Canada) Contributions Audit Committee Paul Mantsch (chair, Spokesperson for Pierre Auger Collaboration) Ethan Schrier (US) Jim Ulvestad (US) Arnold van Ardenne (Europe) Wim Brouw (Europe) Lewis Ball (Australia) Faranah Osman (South Africa) Audit Committee to make recommendations to SSEC by February 2009 In –kind contributions

  19. How is the in-kind contributions register going to be used by the Funding Agencies? What is the “value” to the international SKA program of the submissions to the in-kind register? Should we only consider contributions in the PrepSKA era? and/or Only those contributions that made mention of the SKA in the original proposals? Issues
